By their 10th month of life, typically developing infants produce canonical babbling, which includes the well-formed syllables required for meaningful speech. Research suggests that emerging speech or language-related disorders might be associated with late onset babbling. Onset babbling was investigated 1,536 high-risk infants, at about 10-months corrected age. Parental report by open-ended questionnaire found to an efficient method ascertaining status. Although delays were infrequent, they often genetic, neurological, anatomical, and/or physiological abnormalities. Over half cases not, time discovered prior significant medical diagnoses. Late canonical-babbling may a predictor later developmental disabilities, including problems in speech, language, and reading.
